(devel/R-withr) Updated 2.1.2 to 2.2.0

# withr 2.2.0

# withr 2.1.2.9000

- `defer()` can set deferred events on `.GlobalEnv` to facilitate the
  interactive development of code inside a function or test.  Helpers
  `deferred_run()` (and `deferred_clear()`) provide a way to explicity
  run and clear (or just clear) deferred events (#76, @jennybc).

- `with_connection()` now works when existing objects or connections
  exist with the same names (#120)

- `with_makevars()` now uses `tools::makevars_user()` to determine the
  default user makevars file (#77, @siddharthab).

- `with_options()` no longer uses `do.call()`, so optiosn are not
  evaluated on exit (#73, @mtmorgan).

- `with_package()` no longer has the `help` argument (#94, @wendtke).

- `with_package()` now does not try to detach the package if it is
  already attached before calling `with_package()` (#107)

- `with_preserve_seed()` now restores `.Random.seed` if it is not set
  originally (#124).

- Add `with_rng_version()` and `local_rng_version()` functions to
  change the version of the RNG (#90, @gaborcsardi).

- `with_svg()` documentation now is consistent across R versions (#129)

- Add `with_timezone()` and `local_timezone()` functions to change the
  time zone (#92, @gaborcsardi).

- `with_tempfile()` and `local_tempfile()` now delete recursively
  directories on exit (#84, @meta00).
